The concrete used the D.fab solution by CEMEX and COBOD, with 99% of materials sourced locally and 1% from a central source; printed materials cost under 10,000 euro. The villa (ground floor 130 m2, first floor 140 m2 and a roof annex) complies with Saudi building codes and has smart home systems, nine rooftop solar panels and a heat-reflecting nano coating on the exterior walls. At completion in 2022 COBOD described it as the tallest on-site 3D printed building in the world (COBOD International).
